Qr code scanner from image4/26/2023 ![]() OpenCV is used here for digital image processing. Requirementsīefore proceeding with this Raspberry Pi 3 QR code scanner, first, we need to install OpenCV, Barcode decoding library ZBar, imutils, and some other dependencies in this project. Once OpenCV captures a frame, then we can pass it to a dedicated Python barcode decoding library such as a ZBar which decodes the bar code and converts it into respective information. ![]() OpenCV is used to grab a new frame from a video stream, and process it. ZBar is the best library for detecting and decoding the different types of barcodes and QR codes. ![]() In this tutorial, we are going to build a Raspberry Pi based QR Code Scanner using OpenCV and ZBar library. Also if you want to learn how to interface USB Barcode Scanner with Raspberry Pi and read 2D barcodes with Raspberry pi, then follow this tutorial. To learn more about QR codes and how to generate a QR code, follow our previous tutorial. It is a machine-readable optical label that is in the form of a 2D image and has a different pattern. ![]() QR code (Quick Response code) is a type of matrix barcode that contains information about the item to which it is attached, like location data, identifier, or a tracker that identifies a website or app, etc.
